Predictors of Exercise Training and Physical Activity Adherence in People Recently Hospitalized With Heart Failure: A BRIEF REPORT.

PURPOSE: For individuals with heart failure (HF), frequent attendance at exercise training programs and meeting physical activity (PA) guidelines are significantly associated with improvements in 6-min walk distance. Despite the evidence, adherence to exercise interventions remains poor. The aim of this study was to identify predictors of these 2 variables in patients recently hospitalized with HF.

METHODS: In this substudy of the Exercise Joins Education: Combined Therapy to Improve Outcomes in Newly-discharged Heart Failure (EJECTION-HF) trial, all participants were enrolled in a HF disease management program, including weekly review of a home exercise program for 12 wk. Intervention group participants additionally undertook twice weekly supervised exercise training. Primary outcomes were frequent exercise training program attendance (≥12 sessions) and attainment of PA guidelines (150 min/wk of moderate intensity exercise) at 12 wk. Participant and clinical characteristics were analyzed using a logistic regression model to identify significant predictors of each outcome.

RESULTS: A total of 278 participants provided PA data and 140 contributed attendance data. New diagnosis of HF was a significant predictor of frequent program attendance (OR = 2.3; 95% CI, 1.1-4.7; P = .03). Predictors of meeting PA guidelines at follow-up included new HF diagnosis (OR = 2.4; 95% CI, 1.2-4.8, P = .013), and being physically active at baseline (OR = 2.7; 95% CI, 1.3-5.6; P = .007). Gender, symptom severity, multimorbidity, and disability were not significantly associated with either outcome in multivariate analysis.

CONCLUSION: To improve adherence, specific strategies may be required for patients with decompensated HF and those physically inactive at time of referral.
